[xiongjiabin]

//do some test 求今天的开始时间和结束时间
$timestamp = time();
$beginOfDay = strtotime("midnight", $timestamp);
$endOfDay = $beginOfDay + 60 * 60 * 24 - 1;

echo date('Y-m-d H:i:s e',$beginOfDay);
echo '<br>';
echo date('Y-m-d H:i:s e',$endOfDay);

//这个周末的开始时间和结束时间
$beginOfWeek = strtotime('monday this week');
$endofWeek = $beginOfWeek + 7 * 60 * 60 * 24 -1;
echo '<br>';
echo date('Y-m-d H:i:s e',$beginOfWeek);
echo '<br>';
echo date('Y-m-d H:i:s e',$endofWeek);

$beginOfWeek = strtotime('monday this week') - 60 * 60 * 24 * 7;
$endofWeek = $beginOfWeek + 7 * 60 * 60 * 24 -1;
echo '<br>';
echo date('Y-m-d H:i:s e',$beginOfWeek);
echo '<br>';
echo date('Y-m-d H:i:s e',$endofWeek);

//时，分，秒，月，日，年
$month = 2;

第一个...

$timestamp = time();
echo $startDate = date("Y-m-d 00:00:00 e",$timestamp);
echo $endDate = date("Y-m-d 23:59:59 e",$timestamp );


第二个

$timemsp = time();
$weekIndex = date ( "w", $timemsp ); // 一周的第几天
$endIndex = 7 - $weekIndex; // 周日是几天后
$weekIndex = $weekIndex - 1;
echo $weekStart = date("Y-m-d 00:00:00 e", strtotime ("-$weekIndex day", $timemsp )); // 计算周一
echo $weekEnd = date("Y-m-d 23:59:59 e", strtotime ("+$endIndex day", $timemsp )); // 计算周末


第三个

$timemsp = time();
echo $firstday = date('Y-m-01 00:00:00 e',$timemsp);//开始时间所在月的第一天
echo $lastday = date('Y-m-d 23:59:59 e',strtotime("$firstday +1 month -1 day",$timemsp));//这个月最后一天
